Maxon SM-9 Pro+ Super Metal and ST-9 Pro+ Super Tube

In a previous post, I mentioned that Maxon was the company which made the Tube Screamer and other pedals for Ibanez in the 70s/80s. They are now producing pedals under their own brand and they have just released two new models which will bring memories of the past.

The SM-9 Pro+ Super Metal is not an exact reissue of the 80s Ibanez SM-9. I own an original one and it sports 5 knobs as opposed to the new one which has 4. Also, the 2010 version can be powered with a 9V power supply as well as 18V. In the latter case, it apparently increases “the headroom, frequency range, and dynamic response of the SM-9 pedal”. This new arrival in the Maxon line is clearly geared towards all metal genres, even the most modern, as the sound examples suggest. The old Ibanez SM-9 was also a metal pedal at the time but in an eighties way of course. It was interesting though as it did have some “tube screamer” DNA which does not seem to be the case with the new model.

As to the ST-9 Pro +, ST stands for “Super Tube” to emphasize its Tube Screamer ancestry, not the fact that it is tube based because it is not.  As with the SM-9, the ST-9 Pro+ is not an exact reissue of the 80s Ibanez model. Maxon claims it is based on the circuit of the good old TS808 Tube Screamer but with added flexibility and more gain options. On top of the usual LEVEL, DRIVE and TONE knobs there is a 4th knob to choose the frequency of the “mid range hump” as well as a switch to choose between a classic tone and a “low boost” tone which will fatten your sound. The ST-9 Pro+ can be powered with a 9V or 18V power supply, the latter mode increasing the “headroom, frequency range, and dynamic response of the” pedal. Listening to the the sound clips, I must say the ST-9 does seem to sound like a super charged Tube Screamer.

What is the difference between a distortion and an overdrive?

I have received some feedback suggesting I should do more “beginner” posts about guitar tone and effects. I have also noticed some interesting questions in the google keywords leading to this site. One grabbed my attention: “What is the difference between the Satchurator and the Ice 9 overdrive?”. These two pedals are designed by VOX in collaboration with Joe Satriani and the answer is: the Satchurator is a distortion whereas the Ice 9 is an overdrive.

So what is the difference between a distortion and an overdrive? To put it simply, an overdrive pedal aims at simulating the creamy sound of an overdriven tube amp whereas a distortion does not try to simulate reality and usually offers more gain and is more aggressive.

Way back in the sixties, the only way to get any kind of overdriven tone consisted in just cranking the volume of your tube amp to 10 or 11 if you could. And these amps had no master volume so they were really really loud. Fuzz pedals were the first attempt to reproduce this tone without having to crank your amp. They were really popular in the late sixties but they kind of missed the point and are really a different breed of effect. I will dedicate a post to fuzz pedals very soon!

Later on, talented electronics wizards invented “overdrive” pedals which provided a less harsh tone. Some of them truly approached the singing sound of an overdriven tube amp, so loved by blues and classic rock players. The Ibanez Tube Screamer released in the late 70s is an example of overdrive pedal which became really successful (see my post about it).

Around the same time, other wizards invented distortion pedals which generally offered a raunchier, dirtier, “gainier” tone. The BOSS DS-1 used a lot by Joe Satriani or the Proco Rat are two famous examples.

Then as they did before with fuzz pedals, guitarists combined the tube saturation of their amp with overdrive or distortion pedals, creating entirely new tones… but this is a story for later…

Timeless Classics: The Ibanez Tube Screamer

I thought it was about time to write my take on the most famous overdrive pedal ever: the Ibanez Tube Screamer.

This little green machine and its clones are ubiquitous because they do two things extremely well:

  1. Used against a clean amp, a Tube Screamer will go from a bluesy to classic rock tone that will cut through the mix thanks to a mid-range hump (check out my videos below).
  2. Used against an already overdriven amp, or even another overdrive or distortion pedal, it will push your tone and will give it more body and sustain. This trick was used by numerous rock and metal players in the 80s, before high gain tube amps arrived.

Short history of the Tube Screamer

There is a lot of historical resources about Tube Screamer pedals on the internet, the best being probably Analog Man’s Tube Screamer page. I will give you a short rundown here. The first incarnation of the Ibanez Tube Screamer was called TS808. It was launched in the late 70s as a relatively cheap offering and promised, like every other overdrive and distortion pedal, to give you “the natural overdrive of a good tube amplifier”.

As always, everybody was very skeptical but in that case, it is not far off at all! The Tube Screamer became a piece of choice in the rig of numerous pro players and of course the most famous of them at the time was Stevie Ray Vaughan, who, at some stage, even used two Tube Screamers in series!

The TS808 was quite short lived and was replaced by the TS9 in 1982, then the TS10 in 1986 and the TS5 in 1990. After that, this becomes quite complicated as Ibanez decided to bring back the TS9 in 1993 and the TS808 in 2004 while keeping the cheaper TS7 produced since 1999. I have summarized on this chart the years of production of the different models and this is only for the most common models (more on that later):

Tube_Screamer_Production_Years_superclean

This means that, as of now, Ibanez is selling 5 different Tube Screamers: the TS808 reissue, TS9 reissue, TS7, TS9DX and TS808HW.

In a nutshell, the differences are as follows:

  1. The early TS808 models made between the late 70s and 1982 have become absolute collector items which explains why Ibanez has decided to bring this model back. Because of its circuit and the chips used for its manufacture, it is considered the “best sounding” Tube Screamer.
  2. The TS9 has its followers, it is a bit brighter than an 808 and was the first “old model” to be reissued in 1993 and more importantly the only one available until 2004. This explains why guys like Analog Man were and are still modifying TS9s to bring them to TS808 specifications using carefully selected components (have a look at Analog Man’s website for the technical details). The mod market has not been killed by the release of the TS808 reissue in 2004 as these are still considered in some ways inferior to the modded TS9s.
  3. The TS7 is a cheap alternative and is part of the tonelok series of effects. I had the chance to try one and it does not sound bad at all. It even features a “more gain” mode that the others don’t have.
  4. The TS9DX was launched in the late 90s as a “super Tube Screamer” offering more sonic possibilities. It can be modified too.
  5. The TS808HW is a very recent model and is supposed to be a TS808 with even better components. Is it a gimmick or not, I could not say but this is clearly a response to all the modders and clone makers.

On top of these currently made models, the discontinued TS5 and TS10 can be found more or less easily but the original TS808s and TS9s from the early eighties are very rare and expensive. To make things more complicated, Ibanez, especially in the late 70s and 80s, were in a pedal making frenzy and some of their more esoteric models are more or less related to the Tube Screamer in their conception. I am thinking of the SD-9 or the strange SM-9 which is a bit of a metal Tube Screamer. Mind you these are a departure from regular Tube Screamers but can be interesting nonetheless. Finally, I must mention that a lot of of “boutique” overdrive pedals are Tube Screamer clones with a twist to make them more appealing than the original one (see the “Clones and components” section after the videos).

Which Tube Screamer should I get?

First off, I would say that I own a TS5 which was the cheapest Tube Screamer ever made. Although it does not sound as good as a TS808 or a modded TS9, it does give you a taste of the Tube Screamer tone. It is said that Stevie Ray Vaughan used several models including a TS-10 at the end of his career which gets to show you that you don’t need a TS808 from 1980 to be cool.

Now I think that the safest choice for a reasonable amount of money is either an Ibanez TS808 or a modified TS9. I personally own an Analog Man modified TS9 and it sounds very very sweet as you will see in the videos below (check out the link for purchase information or go straight to www.buyanalogman.com). Mind you, they are not cheap pedals and I would understand if you’d go for a TS-7 as these are less than half the price of a TS-9. I have seen TS-7 for about 50€ whereas a TS-9 is about 120€ and a TS 808 149€.

As to an original late 70s/early 80s model, I think we have now reached the point of irrationality in terms of pricing, these are collector items. If you have the money and the will to find one, go for it but I would not say it is indispensable. Again, check out Analog Man’s Tube Screamer History page if you are in the market for an old one as there is a lot of details which should help you identify a true vintage one from an almost vintage early 1990s reissue. Be warned about one weakness that all these old Ibanez pedals share, it is the switch! The switch of my TS-5 has become very flaky and I have the same problem with my SM-9. These switches can be replaced but if you don’t have the know how, you will have to find someone to do it.

What is all the fuss?

Well I will now try to demonstrate why the Ibanez Tube Screamer is so sought after and why you might well end up adding one to your rig if you haven’t done it already.

First, with a Strat, it can do the Stevie Ray Vaughan tone as well as some more classic rock tones. Alas, it will not give you SRV’s fingers and there is obviously more to his tone than a Tube Screamer but I find you can get pretty close.  In this video, I play my American Classics Custom Shop Strat equipped with noiseless Kinman pickups.

The guitar goes into the Analog Man modded TS-9 Tube Screamer and a Fender Silverface Champ. I show various drive and level settings. At high level settings, the pedal is pushing the amp into breakup, pretty cool! The amp was close miked with an SM-57 and some reverb was added in Cubase 5. At the end, I show briefly what it can do to a distortion pedal (a Pro Co RAT 2 in this case), namely increase the sustain and add some fatness.

And now the same pedal and amp with a gibson SG 61 reissue:

I don’t share the opinion that a Tube Screamer is not very well adapted to Humbucker pickups. My theory is that people say that because the Tube Screamer lets the tone of the guitar through and a Humbucker based guitar will obviously sound totally differently from a single coil based one. You will not get the “quack” of a Stratocaster of a Telecaster but it is interesting nonetheless. And I am talking about using it against a clean amp because against an overdriven amp, a humbucker guitar and a Tube Screamer are an excellent match (ask 80s metal guitarists…).

Clones and components

And because a post about the Tube Screamer would not be complete without mentioning the JRC4558D op-amp chip that was used in the TS808, you will have to know that some of the original TS808 were not made using the JRC4558D but another cheaper alternative called RC4558P and these still sound great. Anyway,  this chip is one of the major differences between the TS808 and the reissue TS9 so for the latter, the mod consists, amongst other things, in replacing the existing chip with a JRC4558D. I will stop here on the subject as I am not a specialist in electronics and there are entire websites devoted to this issues such as here and here.

Although I am not going to mention all the vendors making clones of Tube Screamers, I think I should mention Maxon. Maxon was actually making the Tube Screamers for Ibanez in the early days and they have now a full line of effects including a TS808 clone named OD808 which has gathered a lot of praise. Is it really a clone if it is made by the company that made the originals? 😉

Finally I know that I mention Analog Man a lot in this post, it is only because he is the original Tube Screamer modder and stick to a pure vintage tone philosophy. The other famous modder, Robert Keeley, seems to have less of a pure vintage approach in his Tube Screamer mods which does not mean they are bad at all but I don’t have first hand experience with those, hence will keep my big mouth shut.

Conclusion

There is much more to say about Tube Screamers and I will post follow-ups but I hope you will get from this post why this is such a popular pedal. Actually, to me, it is almost like the natural extension of any electric guitar. So, if you don’t have one, check it out! If you have any questions or remarks, feel free to leave a comment.
